There is no censorship here, you can speak your mind. But as I said on your post just a moment ago, there is a cost to every movement, so taking responsibility for what one says is also necessary. A lot of people seem to think that freedom of speech means there are no responses to what is said, this is not the case.
I think that perhaps we are always free to speak, if we acknowledge the consequences of what we say. In some cases, that might be total destruction, however, history has shown that while rare, some people are willing to pay that cost.
When it comes to the centralized platforms however, there is no "free" there, because they are getting paid - which means that if you threaten their bottomline, they will censor - it is all they can do, they are businesses with the focus on profit.
